I have to ask, what good is more land usable for farming when your rainfall stops? That just leads to more parched land, and less agricultural supplies; drought has already become more prevalent. Consequently rivers dry up which then results in less land usable for farming.

Unfortunately the warming trend has no indication of stopping soon. Warming has so many down sides.

Besides the fact that people are generally healthier when the weather is warmer, with exception only well past the very extremes certain people warn of, warmer weather leads to more land usable for farming, and less extreme storms (as the difference between very warm and cold weather gets narrower) destroying fewer crops, allowing for the world to feed more people.

It’s really unfortunate that the warming trend is expected to stop soon, since the sun is going into a cooler cycle. The warming has so many up sides.
